| description | Provided are a sand-making apparatus, a sand-making method and made sand, which can make effective use of the excessive by-product powder produced at a crushing step. The sand-making apparatus comprises a crusher (10), a first sorter (30) for wind- or sieve-sorting the crushed material into coarse particles (X), fine particles (Y) and powders (Z), and a dust collector (80) for sucking and recovering the powders (Z). Midway of the first selector (30) and the dust collector (80), there is disposed a second sorter (60) for sorting the powders (Z) into coarse powders (Z1) and fine powders (Z2) by the vacuum of the dust collector (80). The mixture of the fine particles (Y) and the coarse powders (Z1) is made into the sand, so that contribution is made to an improvement in the properties of concrete and a reduction of the excess by-product powder. |
